Explanation / Answer

Given that The three capacitance are                   C1=94uF, C2=77uF, C3=61uF From the diagram we know that C2 and C3are in parallel then the equivalent capacitance for the twocapacitors is                   C = C2 +C3                       = 77F +61F                       = 138F Now the capaciatance C and C1 are in series then theequivalent capacitance is                    1/Ceq =1/C1 +1/C                       Ceq = CC1/C+C1                              = (138F)(94F)/(138F+94F)                               = 12972/232                              =55.9137F                              =56F                              =56F
